On a tangential note, mean-spirited and good don't conflict somehow (I guess you can still be morally sound even as a nasty person), and the good trait seems to override most autonomy from the mean-spirited trait.
My town jump 8th gen heir, Lucinda/Cinda/Cici, rolled mean spirited as a child and good when she became a teen, and I do think good tempers mean spirited somewhat.
As a mean spirited fairy, she definitely had her moments!
But having her roll loner as a young adult really helped keep her away from other family members so keeping their relationships intact was a bit easier.
Especially being disciplined, as she spent most of her free time breaking space rock blocks in the basement!
What was most irritating is the nerd group interaction berating others ignorance!!!
That causes no end of trouble between family and friends!!!
On a side note: Jared, who was one of my founders, loved that she inherited his mean spirited trait! And you just know he would!!! lol
